Determinants of persistent low-level viraemia [PLLV, a viral load (VL) of between 50 and 500 copies/mL] have not been elucidated. In a case-control study, we evaluated the influence of micronutrients on PLLV in a population of 454 HIV-1 adults having initiated antiretroviral therapy (ART) between January 2007 and December 2011. Plasma levels of retinol (vitamin A), 25-OH vitamin D2 + D3, vitamin E and zinc were measured at ART initiation in cases (PLLV after 6 months of ART) and in controls (VL <50 copies/mL after 6 months)...

The first-line treatment for psychotic disorders remains antipsychotic drugs with receptor antagonist properties at D2-like dopamine receptors. However, long-term administration of antipsychotics can upregulate D2 receptors and produce receptor supersensitivity manifested by behavioral supersensitivity to dopamine stimulation in animals, and movement disorders and supersensitivity psychosis (SP) in patients. Antipsychotic-induced SP was first described as the emergence of psychotic symptoms with tardive dyskinesia (TD) and a fall in prolactin levels following drug discontinuation...

Purpose Gemtuzumab ozogamicin (GO), a CD33-targeted immunoconjugate, is a re-emerging therapy for acute myeloid leukemia (AML). CD33 single nucleotide polymorphism rs12459419 C>T in the splice enhancer region regulates the expression of an alternatively spliced CD33 isoform lacking exon2 (D2-CD33), thus eliminating the CD33 IgV domain, which is the antibody-binding site for GO, as well as diagnostic immunophenotypic panels. We aimed to determine the impact of the genotype of this splicing polymorphism in patients with AML treated with GO-containing chemotherapy...

To assess how tobacco smoking status affects baseline dopamine D2/D3 (D2R) receptor availability and methylphenidate-induced dopamine (DA) release, we retrospectively analyzed D2R availability measures of 8 current smokers, 10 ex-smokers, and 18 non-smokers who were scanned with Positron Emission Tomography and [(11)C]raclopride, after administration of an injection of placebo or 0.5 mg/kg iv methylphenidate. There was a significant effect of smoking status on baseline striatal D2R availability; with current smokers showing lower striatal D2R availability compared to non-smokers (caudate, putamen and ventral striatum) and to ex-smokers (caudate and putamen)...

INTRODUCTION: Candida africana and C. dubliniensis are closely related species of C. albicans. Current phenotypic methods are not suitable to accurately distinguish all the species belonging to the C. albicans complex. Several molecular-based methods have recently been designed for discriminating among closely related Candida species. The aim of this study was to establish the prevalence of C. dubliniensis and C. africana in vulvovaginal samples with phenotypic and genotypic methods...

Two strains, D5088T and D5095, representing a novel yeast species belonging to the genus Saccharomyces were isolated from oak tree bark and surrounding soil located at an altitude of 1000 m above sea level in Saint Auban, France. Sequence analyses of the internal transcribed spacer (ITS) region and 26S rRNA D1/D2 domains indicated that the two strains were most closely related to Saccharomyces mikatae and Saccharomyces paradoxus. Genetic hybridization analyses showed that both strains are reproductively isolated from all other Saccharomyces species and, therefore, represent a distinct biological species...

Different types of multinuclear half-sandwich rhodium macrocycles and cages were designed and synthesized by using two similar multifunctional hydroxamate ligands (pyrazine-2-hydroxamic acid (NaHL1) and 4,4'-bipyridine-2-hydroxamic acid (KHL2)) featuring one monodentate site and two pairs of chelating sites. The Rh(III)-Pd(II) heterometallic macrocycles were constructed by using the semi-open palladium(II) source (Pd(en)Cl2) with two free acceptor sites. However, only one kind of macrocycle was found when the shorter ligand L1 was used, while in the larger case, various spectroscopic techniques demonstrated that the coexistence of the hexanuclear and octanuclear macrocyles in solution and the proportions of both components depended on concentration and temperature...

PURPOSE: Merkel cell carcinoma (MCC) is a rare but aggressive neuroendocrine tumor of the skin with an increasing incidence. The clinical course is variable and reliable prognostic factors are scarce. Tumor angiogenesis has been shown to have prognostic impact in different types of cancer. The aim of our study was to determine potential prognostic factors, including tumor vascularization, for clinical outcome of MCC. METHODS: The medical records of 46 patients with MCC diagnosed between 1997 and 2010 were analyzed retrospectively...

Neurogenesis continues in the adult songbird brain. Many telencephalic song control regions incorporate new neurons into their existing circuits in adulthood. One song nucleus that receives many new neurons is Area X. Because this striatal region is crucial for song learning and song maintenance the recruitment of new neurons into Area X could influence these processes. As an entry point into addressing this possibility, we investigated the maturation and connectivity within the song circuit and behavioral activation of newly generated Area X neurons...

Repair of interstrand crosslinks by the Fanconi anemia (FA) pathway requires both monoubiquitination and de-ubiquitination of the FANCI/FANCD2 (FANCI/D2) complex. In the standing model, the phosphorylation of six sites in the FANCI S/TQ cluster domain occurs upstream of, and promotes, FANCI/D2 monoubiquitination. We generated phospho-specific antibodies against three different S/TQ cluster sites (serines 556, 559, and 565) on human FANCI and found that, in contrast to the standing model, distinct FANCI sites were phosphorylated either predominantly upstream (ubiquitination independent; serine 556) or downstream (ubiquitination-linked; serines 559 and 565) of FANCI/D2 monoubiquitination...

Controlling luminescence in phosphors able to produce several emissions from different stable excited states determines their use in optical devices. We investigate the color control mechanism that quenches the greenish-blue emission in favor of the red one in the archetype phosphor CaTiO3:Pr(3+). State-of-the-art ab initio calculations indicate that direct host-to-dopant energy transfer (released by electron-hole recombination following the interband excitation and structural reorganization) selectively populates the (1)D2 red luminescent state of Pr(3+) and bypasses the (3)P0 greenish-blue emitter...

BACKGROUND: [(11)C]-L-deprenyl-D2 is a positron emission tomography (PET) radioligand for measurement of the monoamine oxidase B (MAO-B) activity in vivo brain. The estimation of the test-retest reproducibility is important for accurate interpretation of PET studies. RESULTS: We performed two [(11)C]-L-deprenyl-D2 scans for six healthy subjects and evaluated the test-retest variability of this radioligand. MAO-B binding was quantified by two tissue compartment model (2TCM) with three rate constants (K 1, k 2, k 3) using metabolite-corrected plasma radioactivity...

PURPOSE: Oral adjuvant uracil and tegafur plus leucovorin (UFT/LV) is not inferior to standard weekly fluorouracil and folinate for stage II/III colon cancer. However, protein-bound polysaccharide K (PSK) has been evaluated as postoperative adjuvant therapy for colorectal cancer. This report is the first of MCSGO-CCTG, which compared UFT/LV to UFT/PSK as adjuvant chemotherapy for stage IIB or III colorectal cancer in patients who had undergone Japanese D2/D3 lymph node dissection. METHODS: The primary endpoint was the 3-year disease-free survival (DFS)...

Impulsive-compulsive disorders in Parkinson's disease patients have been described as behavioural or substance addictions including pathological gambling or compulsive medication use of dopamine replacement therapy. A substantial gap remains in the understanding of these disorders. We previously demonstrated that the rewarding effect of the D2/D3 agonist pramipexole was enhanced after repeated exposure to L-dopa and alpha-synuclein mediated dopaminergic nigral loss with specific transcriptional signatures suggesting a key involvement of the glutamatergic pathway...
